Min–sup-type zero duality gap properties for DC composite optimization problem

Journal of Inequalities and Applications, 2019
In this paper, we present min–sup-type zero duality gap properties for DC composite optimization problem with conic constraints. Using properties of the subdifferentials of involved functions, we introduce some new constraint qualifications.

Optimality Conditions and Constraint Qualifications for Quasiconvex Programming [PDF]

Journal of Optimization Theory and Applications, 2019
The minimization of upper semicontinuous quasiconvex functions \(f\) in a closed convex set is considered subject to nonpositivity of some lower semicontinuous quasiconvex functions, each described by way of a generator, i.e. as the supremum of a family of quasiaffine functions. For essentially quasiconvex \(f\) (i.e. having no local non-global minima)

On the Convergence of a Smooth Penalty Algorithm without Computing Global Solutions

Journal of Applied Mathematics, 2012
We consider a smooth penalty algorithm to solve nonconvex optimization problem based on a family of smooth functions that approximate the usual exact penalty function.

On alternative theorems and necessary conditions for efficiency [PDF]

In this paper, we establish theorems of the alternative for a system described by inequalities, equalities and an inclusion, which are generalizations of Tucker's classical theorem of the alternative, and develop Kuhn-Tucker necessary conditions for ...
